Interesting coupling logic of feeding network resonator

Click For Summary
The discussion focuses on a resonator composed of 64 gap-coupled small resonators, exhibiting four distinct resonances at 5.7GHz, 6.25GHz, 6.78GHz, and 7.172GHz, with the coupling strength decreasing at higher frequencies. The main inquiry is about methods to enhance the coupling specifically at the 6.78GHz resonance. Participants explore potential techniques and adjustments that could improve coupling efficiency. The conversation emphasizes the importance of understanding the underlying physics of resonator coupling. Overall, the thread seeks practical solutions for optimizing resonator performance at targeted frequencies.

Hello,I have built a resonator which consists from 64 gap coupled small resonators. I have 4 resonances 5.7Ghz (the strongest coupling) 6.25Ghz 6.78Ghz 7.172Ghz as shown below . the coupling of the resonances getting smaller as the frequency rises. Is there a way to increase the coupling on the 6.78Ghz resonance?
Thanks.
